Expansion of Juniperus occidentalis into the sagebrush steppe has resulted in significant changes in understory composition. A consequence of increased J. occidentalis dominance may be a depletion of the seed bank. The p ...

Currently, the of lack information on shrub reestablishment following fire and the wide variability in rates of recovery have lead to uncertainty in using prescribed burning as a management tool in the mountain big sageb ...

In 1978, a ten year project was begun to examine
the synecological effects of livestock grazing riparian
ecosystems. A multitude of biotic arid physical factors,
many which were unique to riparian ecosystems, interact ...

Extensive morphological and growth habit variations have been
reported for bitterbrush (Purshia tridentata), a widespread western
shrub frequently used in range revegetation projects. Hybridization
of this species occ ...

Many streams in eastern Oregon are listed as water quality impaired on the
basis of water temperature. However, it is often difficult to predict water
temperature for these streams even if there are no anthropogenic im ...

Two case studies were designed to study the effects of using off-stream water developments and water gap configurations to modify watering behavior of cattle. There were two objectives: 1) to evaluate an off-stream water ...

Remote sensing and Geographic Information Systems (GIS) are well known tools for
the study of time change analysis in natural systems. However, long-term studies of
riparian systems using large-scale aerial photography ...

Landscape models for elk distribution developed at Starkey Experimental Forest
and Range from 1993-1995 were tested on another landscape during 2003-2005 at
Sled Springs Wildlife Demonstration Area. Using location data ...

On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary ...

Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies ...

Western juniper (Juniperus occidentalis) encroachment has been associated with
increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant
communities and the bird and animal species t ...

Krascheninnikovia lanata (winterfat) is a valuable forage species with an
average of 10% crude protein during winter when there are few nutritious options for
livestock and wildlife. However, excessive grazing througho ...

Woody riparian vegetation is an essential component of riparian ecosystems, responsible in part for the maintenance of functional ecological processes. The plant community composition and distribution provide an indicat ...
